Abstract
The utility model discloses an environment-friendly composite ratproof cable including a plurality of conductors. The conductors are provided with insulation layers formed through extrusion molding by adopting crosslinked polyethylene material respectively. The conductors are provided with an inner sheath formed through extrusion molding by adopting crosslinked polyethylene material. The inner sheath is provided with a reinforcing layer formed by winding a zinc-plated steel tape. An outer sheath is formed through extrusion molding outside the reinforcing layer by adopting nylon material. The environment-friendly composite ratproof cable provided by the utility model has good manufacturing performance and is halogen-free and non-toxic. The environment-friendly composite ratproof cable can guarantee stable operation and generates no harm in processes of production, installation and operation. The use of the zinc-plated double steel tape not only enables the environment-friendly composite ratproof cable to bear a certain axial pressure, but also can prevent the environment-friendly composite ratproof cable from being bitted by rats. A composite ratproof layer is formed by the zinc-plated double steel tape and the highly rigid outer sheath together. The environment-friendly composite ratproof cable provided by the utility model can meet requirements for enabling the environment-friendly composite ratproof cable to operate safely and stably in an environment of 90 DEG C, has no harm on people and the environment, and can meet market requirements effectively.
Description
Technical field
The utility model relates to electric power, control cable field, specifically is a kind of environment-friendly composite rodent-resistant cable.
Background technology
Along with the industry high speed development, traditional cable conductor, insulation, jacket structure can not satisfy needs such as industry, and be special in the serious zone of the plague of rats.The rodent-proof characteristic of traditional cable is relatively poor, when especially cable adopts cable trough to lay, is very easy to receive gnawing of mouse and bites, and causes hidden danger such as cable security, serious accidents such as large-area power-cuts, fire, the safety of serious threat personnel and equipment of causing.Suffer from for eliminating mouse; Traditional protection against rodents way is in cable cover(ing), to add to contain cytotoxic drug chemical agents such as " repellents " etc. and utilize the smell rat destruction; Reach the protection against rodents purpose, but add medicine in the sheath material, can have a strong impact on the mechanical performance of sheath material; And this type of chemicals can produce noxious substance in production and suitable process, personal safety and environment etc. is polluted.
The utility model content
The purpose of the utility model provides a kind of environment-friendly composite rodent-resistant cable, makes cable to suffer from serious area safe and stable operation mouse, and can not produce pollution to the person, environment etc.
The technical scheme of the utility model is following:
A kind of environment-friendly composite rodent-resistant cable; Include many conductors; It is characterized in that: every conductor adopts the cross-linking polyethylene materials extrusion molding to be formed with insulating barrier outward respectively; Described many conductors adopt the cross-linking polyethylene materials extrusion molding to be formed with inner sheath outward, and described inner sheath is outer through the wrapped reinforced layer that is formed with of galvanized steel strip, and described reinforced layer adopts the nylon material extrusion molding to be formed with oversheath outward.
Described environment-friendly composite rodent-resistant cable is characterized in that: described many conductors are copper conductor.
Described environment-friendly composite rodent-resistant cable is characterized in that: in the described reinforced layer, the lapping direction of galvanized steel strip is a left-hand.
Described environment-friendly composite rodent-resistant cable is characterized in that: the hardness of said oversheath nylon material and has self lubricity more than Shao Shi D75 degree.
The beneficial effect of the utility model:
(1), closely connects between each member of the utility model; Constitute one; Insulating barrier and inner restrictive coating all adopt the cross-linked polyolefin extrusion moulding; Reinforced layer adopts the wrapped formation of galvanized steel strip, and oversheath adopts hardness more than Shao Shi D75 degree and have a nylon material extrusion moulding of self lubricity;
(2), the nonmetallic materials of the insulating barrier of the utility model, inner sheath, oversheath all adopt environment-friendly materials to process, manufacturing property is good, Halogen is nontoxic, can satisfy cable stable operation, and in production, installation and running, can not produce any harm.
(3), the use of zinc-plated pair of steel band can not only make cable bear certain radial pressure, can also effectively stop gnawing of mouse to be bitten, and formed compound protection against rodents layer jointly with the oversheath of high rigidity;
(4), the utility model can satisfy cable safe and stable operation under 90 ℃ of environment, can bite preventing that effectively mouse from gnawing again, can bear certain radial pressure, and personnel, environment etc. are not had harm, can effectively meet the need of market.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1; A kind of environment-friendly composite rodent-resistant cable; Include three conductors 1, every conductor adopts the cross-linking polyethylene materials extrusion molding to be formed with 2, three conductors of insulating barrier, the 1 outer cross-linking polyethylene materials extrusion molding that adopts outward respectively to be formed with inner sheath 3; Inner sheath 3 is outer through the wrapped reinforced layer 4 that is formed with of galvanized steel strip, and the reinforced layer 4 outer nylon material extrusion moldings that adopt are formed with oversheath 5.
Three conductors 1 are copper conductor; In the reinforced layer 4, the lapping direction of galvanized steel strip is a left-hand; The hardness of oversheath 5 nylon materials and has self lubricity more than Shao Shi D75 degree.
The manufacture craft of the utility model is following:
Cable adopts the 1st or 2 type of twisted copper conductors, meets the regulation of GB/T3956.Be drawn into required specification according to the above-mentioned copper cash base of wanting, wire drawing is carried out on wire drawing machine and conductor is annealed, the annealing back resistance regulation that should be up to state standards, and the single line surface should smooth, no greasy dirt, cut etc.Concrete condition according to conductor is selected suitable thread reaming machine, and turning to of the speed of twisted wire, the rotating speed of traction and wrapped head is all up to specification.Insulating barrier can be extruded on common extruder; Extrude and will carry out according to operation card, the speed of the working temperature of plastic extruding machine various piece, the rotating speed of screw rod, traction is up to specification, with reference to the suitable mould of the size Selection of core; Can not be eccentric during unwrapping wire, each parts are wanted co-ordination.Stop insulating surface problems such as bubble, flake, fold are arranged.Insulating barrier extrudes the back and gets into crosslinked operation, selects suitable cabler to carry out stranding then, and the direction of stranding is a dextrad.The stranding lay ratio will comply with relevant regulations, and the speed of each parts also will be followed the pertinent regulations of operation card.Inside and outside sheath extrude extruding with insulating barrier.The wrapped mode of employing left-hand of galvanized steel strip, wrapped parameter meets process stipulation.
